Note: If the paise is more than 50 or equal to 50 add 1 to the previous digit, if it is less than 50 keep the previous digit as it is.

__Finding the estimation of the total cost__

Tharun went to
footwear shop with his father. A pair of footwear cost ₹ 99.50 in the
price tag.

Note: If the paise is more than 50 or equal to 50 add 1 to the previous
digit, if it is less than 50 keep the previous digit as it is.

**Tharun :** Appa, what is the cost of the footwear?

**Appa :** ₹ 100

**Tharun :** Appa, the price tag shows ₹ 99.50 but you
said ₹ 100.

**Appa :** Yes tharun. The amount ₹ 99.50 is
difficult to tell. So I rounded off to ₹ 100.

**Tharun :** Appa, why don’t you say ₹ 99 instead of ₹ 100?

**Appa :** Yes, here the amount is ₹ 99.50. If the
amount is more than or equal to 50 paise, round to the nearest value.

**Tharun :** Appa, Suppose if the amount is less than 50 paise,
then keep the value as it is leaving the 50 paise?

**Appa :** Yes Tharun, you are correct. (They bought, footwear
and went happily)** **

**To measure the money accurately,
we can use the approximation**

The approximate value of ₹ 1 is the whole number of before or after.

**Let us try**

Estimate the following rupees (before or after) using the multiples of ₹ 10.

Deepak bought groundnut cookies
for ₹ 24.40, Dhal mixture for ₹ 34.60 and murukku for ₹ 28.75. He prepared to estimate the value to the nearest rupees.
